Yes, many Werrington properties may be suitable for a granny flat, but eligibility depends on the individual block. Under the NSW Housing SEPP, a detached granny flat may qualify for Complying Development (CDC) on lots of at least 450m², provided the proposal meets the required planning standards, including a maximum floor area of 60m² under the CDC pathway. Werrington is within Penrith City Council, with residential areas including R2 Low Density Residential land where secondary dwellings can be permitted. Many established detached properties were developed on larger blocks, often around 550 to 700m², although newer or subdivided lots can be considerably smaller, so lot size should always be checked individually. Another important local consideration is flooding around the Werrington Creek catchment, which Penrith Council has specifically mapped and studied. Checking zoning, flood controls, lot dimensions and site constraints early will confirm whether your Werrington property can use the CDC pathway or requires a Development Application.

A granny flat in Werrington can be approved through a private certifier as complying development when the lot is 450m2 or larger, the secondary dwelling is no more than 60m2 (or 25% of the main house, whichever is less), and setbacks, height and landscaping meet Housing SEPP 2021 standards. This pathway typically takes 10 to 15 business days once documentation is complete. Blocks inside a flood planning area can still qualify, but floor levels and fill must meet the council's flood controls, which we check against the flood certificate before design.
Not meeting one complying development requirement does not rule a project out. Where a block in Werrington is under 450m2, sits in a heritage conservation area, or is affected by a flood planning control, a development application can be lodged with Penrith City Council. Assessment times are longer than a CDC, but the council does approve secondary dwellings through this route.
Werrington is administered by Penrith City Council and assessed under the Penrith LEP 2010. The whole suburb falls within the one council area. Granny Flats X confirms the consent authority for your specific block during the initial property assessment.
